deductive faculty interposes to carry out the principle to its logical consequences. A perfect theory gives dominion over natural facts; and even an assumption which can only partially stand the test of a comparison with facts, may be of eminent use in enabling us to connect and classify groups of phenomena. _From the_ GUARDIAN, _Sept._ 21, 1870. He held some pieces of paper in his hand, but he rarely referred to them. Thoroughly possessed by his subject, his thoughts seemed to flow forth with perfect ease, fresh minted as they were in the most appropriate and perspicuous words. He led his hearers gently and almost unconsciously through the most perplexed mazes and subtlest passages of thought, keeping their ears enchained and their fancy charmed by the endless succession of apt metaphor; and yet, whenever he felt or fancied that their overstrained attention began to flag, he was able to turn aside into light and pleasant banter, and after this interlude of welcome refreshment, to resume again with renewed power the unbroken thread of his serious discourse. It was the manifest work of a master in his art, handling with ease and grace the weighty tools which long use had made familiar to his hand. _From the_ ENGLISH CHURCHMAN, _Sept._ 29, 1870. What astonishes us beyond measure is, that a man of Professor Tyndall’s real ability and earnestness should sneer at the second verse of the Bible, and speak of it as a legend! Why, surely, he has here the very thing which he is searching--the true origin of life. When chaos ruled over the world, and the earth was void of life; it was the Divine Spirit that breathed over the lifeless mass, and light and life sprang into existence. Without stopping to point out the evidence of the highest Christian doctrine in this passage, we have at least the solution of the enigma of the origin of life, in the revealed truth that it was caused by the Creative Spirit. _From the_ RECORD, _Sept._ 23, 1870.
